PROCESS OF MAKI Ne HEADED NAILS.

SPECIFICATION forming part of Letters Patent No. 355,839, dated January11, 1887.

- Application filed October S, 1886. Serial No. 215,656. (No model.)

To all whom it vnay concern:

Be itknown that I, FREEBORN F. RAYMOND, 2d, of Newton, in the county ofMiddlesex and State of Massachusetts, a citizen of the United States,have invented a new and useful Improvement in Headed Nails and Processof Making the Same, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart of this specification, in explaining its nature. I

The invention comprises a headed nail made from a fiatnail plate orstrip and having ahead projecting upon all sides thereof, a shank theupper part of which may be square, rectangular, or round in section, andthe lower part of which is square or rectangular in section. The nail ismade from the flat plate or strip of metal by first forming or cuttingfrom said strip a nail-blank having a shank and head forming extensionsprojecting from each edge at the end thereof of the same thicknessas theshank; second, in submitting the blank thus shaped to the operation ofdies, whereby the head-forming extensions are shortened and thickenedand a head extending upon all sides of the shank produced, and, ifdesired, the shape of theupper part of the shank changed from arectangular to an oval or round form.

In the drawings, Figure 1 is a plan view of the nail-plate. Fig. 2 is aplan view of a nailplate and one nail-blank cut therefrom. Fig. 3 is aview of two blank strips cut or formed from a nail-plate. Fig. 4 is aperspective view of a nail-blank. Figs. 5 and 6 are views of complete orfinished nails.

In producing the tack blank it may be formed either by cutting blankssingly from the plate or by first forming a strip of blanks havingthehead-forming portions of the blanks connected, and I have representedboth ways in the drawings.

is then submitted to the operation of dies, whereby pressure is broughtto bear upon the edges of the head-forming sections b, to upset them andform them intoa head that shall be oval, round, or square, and shallextend uniformly or substantially uniformly from all sides of the shank.The shank or upper part of the shank of the blank may be at the sametime submitted to the same forming operation of dies in extension of thehead-forming dies, whereby its form shall be changed from a thinrectangular shape to a round, square, or oval shape, and I haverepresented in Fig. 5 ablank which has had its head only submitted tothis forming operation, and in Fig. 6 a blank whose head and shank havebeen thus treated.

I would say that for the purpose of obtaining the flat thin blank it isnot necessary to first form a connected strip of shanks, at

the thin blanks can be punched directly from a plate or sheet of' metalone by one as they are required. (See Fig. 2.)

in cross-section, a round or square shank, and a head extending upon allsides thereof.

The dies employed must exert their prinforming extensions of the blankin upsetting them to form the head, and against the edges of the shankin thickening it or reducing it to a curved shape.

The same process can be used in making other pointed fastenings.

Having thus fully described my invention, I claim and desire to secureby Letters-Patent of the United States The process of making headednails orsimilar fastenings, consisting in forming from a flat thin nailplate a blank,- having a long shank of uniform thickness throughout andtapering edges, and also extensions from said the shank, and, second, incompleting the nail by subjecting the blank to the action of diesadapted to act against the ends of the head-forming sections of theblank, whereby lateral pressure'to form a head extending upon all sidesof the shank, substantially as described. 17
